Answer:
434 -49π ≈ 280.1 cm²
Step-by-step explanation:
The shaded area is the difference between the enclosing rectangle area and the circle area.
The rectangle is 14 cm high and 31 cm wide, so has an area of ...
A = WH
A = (31 cm)(14 cm) = 434 cm²
The circle area is given by ...
A = πr²
A = π(7 cm)² = 49π cm²
__
The shaded area is the difference of these, so is ...
shaded area = rectangle - circle
= (434 - 49π) cm² ≈ 280.1 cm²
Answer:
1. x= 8
2. x= 6
3. x= 7
4. x= -8
Code: BECI
Step-by-step explanation:
You could simplify 255
100+100+55
for each hundred there's 15$ earned so 15×2 =30$
there's 55 left and 1 till 99 =0.10 each
55×0.10=5.5$
30+5.5=35.5
in short the answer is 35.5$
Answer:A = 6s²
a) s = 3in, subtitute
A = 6 · 3² = 6 · 9 = 54 (in²)
b) s = 1.5 m, subtitute
A = 6 · 1.5² = 6 · 2.25 = 13.5 (m²)
Step-by-step explanation:
(40+16)=56 or
(4x10)+(4x4)=56 or
4x(10+4)=56
